Specification of Letters Patent.

Patented July '31; 1966:"

Tv wZZ whom it may conoern: 1 Be it-known that I, GEORGE KING TYLER, a subjiec't of theKing of Great Britain, (having declared my intention to become a citizerrof thefUnitedStates,) residing at Tawas City, in thei-county of Iosco and State of Michigan, have inventedtcertain new and useful Improvements in Skewer-Pointing Machinesgand I: do hereby declare the following to'be-a" full, clear,.and exact description of the invention, such as will enable others skilled in-- the artto which it appertairisto make and use the same. 7

This-invention is a 'machine for pointing skewers; and the improvements consist in certain :constructions and combinations and theize'quivalentsthereof, as vwill be fully set forth-in this specification. 1 v

Theiobjects'are to provide in askewer-machine means for simultaneously pointing both ends of the skewer and to form the pointswit-h a double taper''that is, with'a conical point and a portion between the conical point and the body of the skewer, said portlon being in the form of a truncated-cone.

Further objects are to so arrange the pointcuttersthat they may be adjusted to suit variouslengths of skewers-'and't'o so mount the skewerzconveyerebelt relatively to the revolvingcutters that the cutters may be 1 raisedi-or lowered relatively to the skewers,

thereby; compensating for wear of the knives and keeping the skewer-points of uniform also showing the arrangement of thecutterknives relatively to the stationary guides over-which the' skewers roll. Fig. 2; is a transverse section, on a reducedscale', the sectionbeing taken on the line w a: of Fig. 1.

cutter-heads are secured tothe-shaft {bymeans oftapered keys or feather 5, so they a may be adjusted toward or fromeach'other lengthwise the shaft. ,BetWeen the cutter heads 1 1s locateda; pair-of; stationary guides 6, the upper surfaces of which'are curved Z skewer, showingthe double taperedpoint and F the arrangement relatively thereto of'the cutter-knives by which the ointis formed;-

The cylindrical surfaces of theseguides are preferably knurled or roughenedrfOr ;apurpose which willapresently be} described. The guides 6 have on thesides o -the-frame43 beingzslidably mounted thereon by means of dovetailed guides 14 so that the statiOnary guides- G may toward from h Q herlength' wise the frame 4. Each'guidehasa hub' 6. andz-thehubs of the two-guides are'arranged opposite each other, as shown in Figs; 1 and 6. A loose ringtil is fitted. toeach; of-wthe hubs 6 as shownin Fig; 1, and a pulley=8in v rojecting: bases 16*, that rest the form of an annular rim issecuredato and I connects the rings 7 by means oftl1'escrews 7 or any other suitable'means, 1

A .conveyer belt 9 runs onthe'pu-lley 8, which, together "with the rings 7, forms a loose pulley revolving on the hubst under the action ofthe-beltf The construction-of thebelt 9-is illustrated in :Fi 8, 2, 3 andi4 where 9 isa flat sheet-ofmeta bent into substantially' the form'iof a letter S and secured to thenbelt by rivets QLor otherwiser- The pockets are assembled by interlockingwthe upwardly-projectin members of one pocket with the downward y-projectingmembers-of the next pocket thus-formingyielding. joints betweerr consecutive pockets, and permitthe belt and pockets to travelaround too tin pulleys without I bending: the material: ear

which the pockets aremade; v r f In practice "skewers :are deposited in the pockets93-a's shown in FigsL -Q and-r3 -and are carried: up around the; pulley 8., where the lower surface of each skewer comes; incone tact with the stationary knurled faces'o'f the guides 6. As. the. belt travels around the pulley 8 the skewers are revolved by reason of their contact with the fixed guides 6. To insure their proper contact with the guides 6, and to thereby produce the positive rolling movement of the skewers, I provide a presser-belt 10. (Shown in Fig. 3.) This belt is mounted on idler-pulleys 11 and 11 and a third pulley 12, by which the belt is driven. The bottom of the pockets 9 as they pass around the pulley 8 are slightly below theperiphery of the guides 6. By this means each skewer is made to roll around the periphery of the guides 6, revolving meanwhile in the pocket 9 and not in contact with the bottom of the pocket. As the skewer travels up on the belt it rests in the bottom of the pocket but as soon as it comes in contact with the knurled face of the stationary guide the skewer is raised a little, so that it clears the bottomof the pocket. The pressure-belt presses the skewer down upon the knurled face of the guide, but does not press it down upon'the bottom of the pocket of the belt. An important object of the belt as it goes around the pulley 8 is to keep the skewer straight-that is, parallel with the axis of the shaft 2. Previous to reaching the pulley 8 the office of the belt is to convey the skewers up, keep them straight, and deliver them straight under the pressure-belt.

The two ends of the skewer project beyond the guides 6 and into the cutting-circle of the two cutter-heads 1 1. The knives or cutterheads 1 1 are preferably arranged as shown 'diagrammatica ly in Fig. 5, where 13 is the cuttin edge of the blade, set at a proper angle to orm the conical point 14 of the skewer, and 13 is the next suceeding knife on the head 1, set at an angle to form the en'lar ed or truncated conical portion of the point. y

- this device a sharp point is produced on the skewer, yet the long slim point heretofore common is avoided and a large strong point produced.

When it is desired to point skewers of greater length, it is only necessary to loosen the keys 5 to slide apart the heads 1 1 along the shaft 2 and also to slide apart the stationary guides 6. The pulley 8, which is preferably a split pulley, is removed from the rings 7, 7, and a'- wider pulley or rim is substituted therefor.

To compensate for wear of the knife-edges, which tends to decrease the diameter of the cutting-circle of the heads 1 and also to admit of cutting skewers of difierent diameters, I provide an opening 6 in the guides 6, through which the arbor 2 passes. This opening is considerably larger in diameter than the shaft 2, and t e shaft and the cutter-heads may therefore be adjusted in height by lacing shims or liners under the boxes 3 or fiy making the boxes-adjustable in any suitable manner.

skewer reaches the knives.

In the accompanying drawings I have shown the belt 16 for driving the arbor 2 and have mounted the lower end of the conveyerbelt 9 on the pulley 17, which in turn drives the pulley 12 through the medium of the shaft 18 and suitable bevelears 19 and 20. Simultaneous movement of the conveyerbelt 9 and the presser-belt 10 is thereby produced. I do not, however, desire to confine myself to the particular form of driving mechanism shown in the accompanying drawings, as any other suitable device may be employed without departing from the spirit of my invention.

As is usual in devices of this sort I provide a hopper 21 above the conveyer-belt 9 and fill the belt-pockets 9 by skewers deposited in the hopper 21.

One advantage of the long conveyer-belt 9 is that in case a defective skewer is delivered from the hopper 21 to the belt the o v erator can detect it and pick it out before tffe This cannot be done in machines having the hopper close to or directly above the knlves.

By the means above described I have produced a simple, inexpensive, and efficient machine for pointin skewers and for producing a double-tapere point, as shown in Figs. 1 and 5.

What I claim as my invention, and desire to secure by Letters Patent, is as follows:

1. In a skewer-pointing machine the combination of a pair of cutter-heads mounted on a spindle and adjustable lengthwise thereon; a pair of guides in proximity to said outter-heads, said guides having roughened surfaces concentric with said cutter-heads; a projecting hub on each guide; a loose pulley mounted on said hubs; a conveyer-belt having pockets, the bottoms of which are slightly below the faces of said guides, and adapted to roll skewers around said pulley in contact with said guides; together with a presserbelt for holding the skewers in contact with the guides.

2. In a machine of the class described, the combination with a suitablysupported driven cutter-head, of a guide provided with a convex surface of less radius than the greatest radius of the cutter-head and located in alinement therewith and adjacent thereto, a conveyer for the work to be treated, the bed of the conveyer being received on a plane beneath the convex face of the guide as the work is presented'to the cutters and means for retaining the work in simultaneous engagement with the cutter-head and guide.

3. A woodworking-machine comprising a cutting or abrading mechanism, a stationary guide having a convex surface located in lateral alinement with the mechanism, and a conveyer for supplying work to the guide and mechanism, the guides operating to partially remove the work from the conveyer during the progress of the work past the mechanism and means for retaining the work in engagement with the mechanism.

4:. In a machine of the character shown, the combination with a cutter, of a convex guide, the height of the guide being slightly less than the radius of the cutter, aconveyer comprising an endless member and separate I pockets secured thereto, the pockets overlapping each other, the pockets adapted to receive the work, the bases, of the pockets lying beneath the plane of the guide, the sides of the pockets extending above the plane of the guide, whereby when the work engages the guide it is lifted off the base of the pockets and means for retaining the work in en- I gagement with the guide and cutter. I

5. A woodworking-machine comprising a cutting or abrading mechanism, a stationary guide located laterally of and extending parallel with the mechanism, means for feeding work to the guide and mechanism and means for retaining the work in contact with the.

guide and mechanism, the guide capable of a fixed lateral adjustment toward and from the mechanism and independent of the feeding means.

6. In a machine of the character. shown, the combination with a shaft and a cutter mounted thereon, of a sectional normally stationary guide, through which the shaft extends, hubs formed on the sections of the guide and projecting toward one another", rings loosely journaledon the hubs, a rim secured to the rings, a conveyer passing over the rim for feeding the work to the guide and cutter, and means for retaining the work in contact with the guide and cutter.

7. In a woodworking-machine, the combination with a cutting or abrading member,

alinement with the member, a conveying means for supplying work to the member, the guides adapted to support the work during its passage past the member.

8. A woodworking-machine comprising a cutting :or abrading member, a guide located.
